Description
Advantages of tungsten alloy:
Tungsten alloy has many special properties, such as small size with high density, high melting point, high hardness, excellent wear resistance, high ultimate tensile strength, good extension, heat resistant, good thermal stability, easy processing, corrosion resistance, good shock resistance, high radiation absorption capacity, excellent impact and crack resistance.
Tungsten shielding Introduction:
Tungsten shielding products could be applied on medical shielding and nuclear shielding. Tungsten shielding products provides high-density tungsten based products. We can manufacture parts based on your drawings. Tungsten is very difficult to machine which makes our experience working with tungsten important and enables us to be a reliable partner for your tungsten needs.
Application:
- Guarantees minimum exposure of radiations into environment during the production of X-ray radiations.
- Use in the cancer therapy machines for rendering protection
- Allow shielding to many elements of the detectors
- Also, offers protection against gamma rays
- Shielding for Co60 and other radiation
- Shielding syringe for liquid medicine radiation
- Autocollimator and tungsten collimation bar for medical lineal accelerator
- Flaw detector
- Radioactive source containers
- Large container inspection devices
- Tungsten alloy containers, such as tank, box for storing radioactive materials
- nuclear industry and container system inspection
- Nuclear shielding wall etc
